By all accounts, Grand Army Plaza – designed by the Central Park dream team of Frederick Law Olmsted and Calvert Vaux and open as the gateway to Prospect Park since 1916 – compares favorably with Paris’ panoramic Champs Elysées and other classic boulevards.

Even back in the 1920s, the city saw fit to install a “Death-O-Meter” at the rotary – to slow drivers and update fatalities.

But that was then, and this is close: The Grand Army Plaza Coalition yesterday announced the hiring of Danish consultant Jan Dehl, who has a plan: build a tunnel, create a low-speed area, make traffic flow along an outer ring and revisit a 1987 proposal to narrow roadways and increase pedestrian access.

Transportation officials vowed to review the ideas but said nothing of resurrecting the Death-o-Meter.
